the best way is to just tap on it ,
you can pretty much tell a cheap piece
of steel from a cast iorn one that way....
I would like to hear how they claim is the
best way to break one up???
Usually you want ot take all mirrors and
hanging things off the near by walls.
then you take a large piece of carpet and lay it
in the tub ...for protection.
then you take the sledje hammer and whack the hell
out of the tub through the carpet...
breaking iti into managable pieces....
what is the proper way to do this??
